Soil nitrogen exists largely as organic matter, including plant liter, dead animal matter, and microbial necromass. About 90% of soil organic nitrogen is proteinaceous material that is too large for plants and microorganisms to assimilate directly. Protein depolymerization therefore plays a critical role in mobilizing this organic source of nitrogen,...
Proteinaceous compounds are abundant forms of organic nitrogen in soil and aquatic ecosystems, and the rate of protein depolymerization, which is accomplished by a diverse range of microbial secreted peptidases, often limits nitrogen turnover in the environment. To determine if the distribution of secreted peptidases reflects the ecological and evolutionary...

“An undeniably vast portion of American history is attributed to people of color. But these stories of discoveries and researches, resilience and liberation all seemed like missing pieces to the puzzle that is America.” (Vo-Nguyen). This speaks to the experience of how the stories, lives, and contributions of their communities...
Tomato is considered to be one of the most important vegetables for its value as a source
of nutrients and antioxidants, and as a model crop for biological research, including seed
biology. In this thesis, tissue-specific gene expression and its regulation in tomato seeds
were analyzed to understand the mechanisms...
The demands of the healthcare system on its employees are heavy and intense. Long working hours, high-stress environments, and emotionally exhausting situations can lead to burnout. This is particularly a constant concern in emergency medicine. Burnout has been associated with impacting well-being and performance. There is also an interest in...
